后室迷失之境Backrooms：The Lost changes
Today we’d like to share with you the latest Level 1 design for Backrooms: The Lost (This is the Fandom-version prototype.)
All screenshots below are captured from in-game footage—
LEVEL 1: The Open Plaza
Currently, the open plaza is about 50% complete, and we’re still refining details.
The design is based on the Backrooms Fandom Level 1 setting.
LEVEL 1: The Penrose Infinite Staircase
This is one of our original creative twists in Backrooms: The Lost.
Is it going up, or going down? Up or down?
Can you tell me?
LEVEL 1: The Decayed Stairwell

In addition to referencing the Fandom version,
we aimed for the raw, unfinished look of a concrete shell.
For the lighting and atmosphere, we drew inspiration from classic Thai horror films.
Can you guess which one?
LEVEL 1: The Bottomless Parking Lot
Experienced players will notice this immediately—
it’s a classic example of liminal space design,
a hallmark of the Backrooms aesthetic.
LEVEL 1: The Warehouse Parking Area
As a typical element of Level 1,
we built it with concrete floors + incandescent lamps + a cold, empty vibe.
Do you like it?
That’s our current development progress for now. We’ll continue to share updates with you, roommates, whenever we have new info.
